To comply with GST requirements, all those under the GST regime must file GST returns (GSTR). These returns specify income details for clarity and calculate the amount of tax you are required to pay to the government. It is important to remember that you will need GST-compliant invoices for sales and purchases if you wish to file GST returns. When it comes to filing your taxes, GSTR 1 is one of the necessary forms. This is because the information you file under GSTR 1 is used as a base for all other forms to be auto-populated. To understand this better and comply with GST norms, read on for more information on GSTR 1.

What is GSTR 1?

GSTR 1 is a form that accounts for the outward supply of goods. It is a monthly or sometimes quarterly return that you have to file to account for your business. It means that any individual involved in the supply of goods needs to specify the supply and recipient details. By doing so, the returns for the inward supply will be auto-populated with the details filed in GSTR 1. Since GSTR 1 is the foundation that affects other GST forms, you must fill it with utmost care.

Filling the GSTR 1 form: Explained

GSTR 1 has 13 different sections that need to be filled out by you. However, a few of these may be auto-populated. Let us look at the 13 various fields below.

  • An auto-populated result for the GSTIN of the person filing the return.
  • An auto-populated result of the name of the person filing the return.
  • The total turnover of the previous financial year needs to be filled once, and then will automatically auto-populate the form with the closing balance henceforth.
  • Details of the outward supplies to a registered person are taxable.
  • Details of the outward supplies (inter-state) to an end consumer where the transaction exceeds Rs. 2.5 lakh.
  • Zero-rated supplies as well as deemed exports (to EOUs and SEZs) along with details of invoice, shipping bill, or bill of export.
  • A total consolidation of all outward supplies for the month, including through e-commerce operators and up to Rs. 2.5 lakh.
  • Details of exempted, non-GST, and nil supplies if they are not already mentioned.
  • Any revisions/ amendments that need to be made towards the outward supplies of previous tax periods, including debit/ credit notes and refund vouchers.
  • Details of outward supplies are listed on the basis of HSN codes.
  • Any tax due to advance payment received.
  • Any taxes paid for the previous periods or reporting periods.
  • Documents issued during the period for which GSTR 1 is being filed including invoices, revised invoices, credit notes, and debit notes.

What do you need to file GSTR 1?

You need to have the below documents and information ready with you to file GSTR 1.

  • A valid and genuine Goods and Services Tax Identification Number (GSTIN).
  • The user ID and password to sign into the portal.
  • A valid digital signature certificate (DSC) unless you can e-sign the form as per your categorisation as a supplier.
  • Aadhaar number if you are going to e-sign the form.
  • Access to the mobile number mentioned on your Aadhaar card.

What are the late fees that can be incurred on GSTR 1?

It is important to remember that GSTR 1 also has a due date by which it needs to be filed, like all other tax filing forms. To meet this GSTR 1 due date and avoid late fees, you will need to file GSTR 1 by the 10th of the following month. It means that you will need to file returns for January by 10 February and so on. However, this is only in terms of businesses with more than Rs. 1.5 crore turnover. If you have a turnover less than this, you will need to file GSTR 1 quarterly by the last day in that particular period.

If you do not submit GSTR 1 before the GSTR 1 filing date, you will need to pay the penalty for failing to comply with these rules.

These late fees are Rs. 50 or Rs. 20 per day. The latter is applicable if you have nil returns to file and delay submitting GSTR 1. Recently, for the period July 2017 to September 2018, the government has waived this fee entirely. If you have paid it, the sum will be refunded to your electronic cash ledger for future use.

Filing GSTR 1: What do you need to keep in mind?

Filing returns for your business can sometimes be a little tricky. However, if you are careful, you need not worry about confusion or mistakes. So, look at a few pointers to keep in mind while filing GSTR 1.

  • Ensure you have entered the correct GSTIN code and HSN codes to avoid any discrepancies.
  • Confirm whether the transaction falls under the intra-state or inter-state category.
  • You can change uploaded bills multiple times; however, you will not be able to change an invoice once the return has been submitted.
  • You cannot revise the return once you have submitted the same and need to make any corrections in the next month’s GSTR 1.
  • GSTR 1 is part of GST registration and GST return filing and you do not have to pay any taxes until the filing of GSTR-3B.
  • Upload invoices at various intervals during the month to avoid bulk uploads.
  • Companies like LLPs (limited liability partnerships) and FLLPs (foreign limited liability partnerships) are obligated to provide a digital signature certificate (DSC).
  • Suppliers such as proprietors, partnership concerns, HUFs, and others can E-sign the GSTR 1.
  • If the point of supply has changed and is now in a different state, the SGST charge will be as per the new state.
  • Once a recipient has accepted the details in the GSTR 1, you cannot make any changes to the tax invoice. However, you can issue a credit note or a supplementary invoice to make room for the changes.
  • File GSTR 1 easily by using third-party software.

While you may already know simple procedures such as how to calculate GST, now you are sure to have a better understanding of the finer aspects of GSTR 1.
